Last week I talked about my ideas for an stat system for the RPG I’m designing. Since then, I’ve talked to a few people about my ideas and I’ve had a proper think on the subject. I ended up doing some mock rolls and firing up the old spreadsheet to get an idea of the probabilities and as it turns out, it’s not really workable. If you’re interested in the process, you can see some of my notes here.
What I ended up realizing is that for a roll-under system like what I had in mind, good old D12 just doesn’t have the range necessary to be a good fit for a roll-under system. The delta between a 50-50 chance and nearly impossible to fail is only 6 points and given that I want characters to at least feel competent, that puts the range of stats characters can have in a very narrow band.
So, keep what I learned, throw everything else under the bus and start over. I suspect that will become a theme as I write this system. Come up with an idea, give it a test and then chuck it out for sucking. So on to idea v0.2
